I am currently using 4 TM751 transceivers to receive RF from IR sensors and SS13A wall switches. Some of the changes I would like to make will add additional house codes in RF. I would like to use a CM15A just as a transceiver, no timers/macros/attached PC.
I cleared a CM15A. Created an empty runtime file. Selected transceiver house codes in the configuration of AHP. Did an update and downloaded the empty file. Moved the CM15A to a desired outlet. Testing with a couple of SS13As, the RF signal did not transfer to PLC.
OK – I have three CM15A. I am not sure which one I used for the trial. The first one, I purchased in 2006 to upgrade to AHP. The second one I purchased in 2009 because the first one stopped working. No macros, no timers controlling lights…. The second on failed in 2011. Looking at the X10 forum and just searching Google to find an answer to why the CM15As failed, A tip (don’t remember where) that said the batteries and battery cover causes heat buildup and resulting CM15A failure. So, when I purchased the third module, I did not install batteries and left the battery cover off. X10 has worked mostly OK. No catastrophic failure like in the past. Have not seen any more Forum comments regarding this problem recently.
I have been running trials of various HA software packages. All three modules will generate and receive PLC commands. The RF side I am still sorting out.
As a test, I took two SS13As: one set to B1-3; the second set to D5-7. I have a TM751 transceiver set to B. Switch B1 activation shows in the log and the module toggles. D5 shows in the log, but does not toggle the respective module. When I add another TM751 set to D, switch activation toggles the module. It appears that the CM15A(s) are decoding the RF signal but not resending out as a PLC.
I read number of threads on Tuicemen’s X10 Issues? Please Read This First! On X10 Forum from 2006 that described the functionality of monitored and transceiver. If I understand correctly, the CM15A should act the same as a TM751. Mine are not. When I have a corresponding module in AHP then the module will toggle. So, is this a defect (burn out) in the CM15A(s) or is this the proper function?
